Ill 



the spines becoming larger toward the distal end. The outer lobe of the 

 maxillipeds is armed with numerous long strong setae; the inner lobe is 

 armed in the distal part with 2-4 strong setae . 



In pereopods III and IV the 5th and 6th segments bear short setae on 

 the distal surface. The 6th segment of pereopods III-VII is longer than 

 the 5th; in pereopods V-VII the 5th segment is equal to the 4th, the 6th 

 segment of pereopods V-VII is longer than the 5th but not broadened 

 distally. 



In uropods I the basipodite has a highly convex anterior margin 

 and both rami are tapered. In uropods II the basipodite is broadened 

 distally and equal in length to the endopodite and both rami are tapered. 

 In uropods III the basipodite is short and broad, the two rami equal in 

 length, broadly lanceolate, and terminally acute. The broad oval telson 

 reaches the distal margin of the basipodite of uropods III. 



Distribution: Known from the northwestern part of the Pacific Ocean 

 north of 40° N and from the Indian Ocean (northern tip of Sumatra). It 

 is found in catches from depths of 0-400 and 0-1,000 m and in catches 

 from the 3,500-5,000 m layer. 



97 3. Chuneola spinifera Vinogradov, 1960 (Figs. 35, 36) 



Vinogradov, 1960b: 251. 



One sexually mature female 41 mm long known. 



The color of the unfixed specimen was pale pink with darker pere- 

 opods and urosoma. 



The anterior somites of the pareon bulge markedly. The integument 

 is semitransparent and thin. Spinelike processes occur in the ventral part 



98 of pereon somites II-IV, one pair on each somite. The posterior dorsal 

 margin of the pereon somite VII and especially somites I-II of the pleon are 

 cylindrical. The head extends into a strong triquetrous vesicular rostrum 

 that is terminally rounded; it is equal in length to the first two pereon 

 somites. The eyes are small but distinct. The mouth cone is well developed. 



Antennae I are inserted in broad depressions and only slightly project 

 beyond the vertical frons; they are shorter than somite I of the pereon; the 

 peduncle is half the length of the flagellum; the two distal segments of 

 the flagellum are rudimentary, as in C. major. The vesicular antennae II 

 are slightly shorter than antennae I, their distal segments very small and 

 entirely situated in the depression of the preceding segment. 



The mandibles have a finely denticulate cutting edge; a small area on 

 the inner surface of the mandibular body is covered with short setae. The 

 outer lobe of maxillae I is broad, with a straightly truncated apex bearing 

 five strong spines; the inner lobe is small, oval, and densely covered 

 with short setae, among which some are prominent by their length and 

 thickness; the palp has three apical spines and a row of spines on the 

 inner margin. Maxillae II are the same as in other species of the genus.
